Effect of heat input on microstructure and mechanical properties of GH159 and GH4169 dissimilar joints by laser beam welding
Co-based superalloy GH159 and Ni-based superalloy GH4169 have been successfully joined by laser beam welding and the effect of heat input on microstructure and properties of dissimilar joints were investigated systematically. The results showed that weld seams exhibited a nail shape and full penetra...
